I use my "George Foreman Grill to prepare my Quesadillas. If you do not have one you can use a griddle on your stove top.

Pre-cook your veggies on the grill or griddle till just getting soft. Onion will appear almost translucent.

Put 1 tortilla on the hot grill.

Add "Chicken", Grilled Veggies and Cheese

Place another tortilla on top of the bottom loaded one.

Close lid on George Foreman Grill and wait.....

Check in about 45-60 seconds. You want it to have brownish grill marks on it and also to be firm to touch.

If you don't have a "George Foreman Grill" you will wish you did. Cause you will have to flip you loaded Quesadilla when using a griddle. But the same look of the Quesadilla is the same. Toasty and Firm.
